    Abstract

    With decreasing powder particle size, formation of intermetallic compounds was suppressed in gas-atomized Al-14wt.%Ni-14wt.%Mm alloy powder, powders with < 26 mum particle size consisted of alpha-Al particles embedded in an amorphous matrix. The hardness decreased with increasing particle size and also on heat treatment due to particle coarsening and/or crystallization of the remnant amorphous phase. (C) 2001 Acta Materialia Inc.
